Make sure you do the second part of #3 and power off and UNPLUG all NMT units you do not want to synch

1. Attach the provided antenna to the RF antenna port at the rear panel of your NMT.
2. Remove the batteries from the RF remote control.
3. Power ON your NMT and wait for it to complete its loading process.
(Power OFF and unplug the power cord of all other NMTs that you do not intend to
synchronize in this synchronization exercise.)
4. Re-insert the batteries into the RF remote control. By inserting the batteries, the RF
remote control will now synchronize with any RF-compatible NMT that is active.
5. The RF remote control and NMT is now synchronized and will function properly.

Anyone who does a modicum of research before buying a c200 would be THRILLED to that you replaced the power supply as it is not an "if" it will fail, but a "when".
And I feel that shipping and time involved to repair the old pos psu is quite a bit more than a "few $ repair".

Hopefully someone will come along with a suggestion as to a repair source ,rather than arguing the pros and cons.

Seemed to have turned into a ethics question..

My fault for asking such a stupid and silly request... Clearly I have no idea what I am doing here.. Gone are the days at forums where peioople were friendly , and did not just try to shoot everyone down.. I will retire to my own silly world..

Sure, take the blown power supply to any reputable electronics repair shop. They will happily do a diagnostic on it to find out what is wrong. I had two quotes from reputable places in my area. The cost would have been diagnostic time of about $50 plus the actual time worked on the repair plus the cost of the parts needed. Both places said it would be about $100 give or take.
The power supplies are not overly complicated devices and nearly any reputable electrician should be able to diagnose and repair them.

Hope that is helpful enough for you...

I have 2 C200 players. The power supply failed on one of them. I repaired the failed supply for under $2.00 in parts cost. In my case, 3 capacitors had failed. This is a very common failure. To identify failed capacitors, remove the power supply from the C200 and take off the cover. Then look for domed or leaking capacitors. They are cheap and available from Digikey. You'll need soldering skills and appropriate tools to do this yourself, but it's not difficult job. It helps if you have an understanding and familiarity with electronic circuits (or a friend with these skills).
